A novel concept of a three-beam antenna array operating over a one-octave frequency range is proposed in this paper. The antenna array allows stable beams’ direction and beamwidths. To achieve constant radiation patterns, the antenna elements are appropriately spaced and fed by a network consisting of a broadband Butler matrix to which outputs dire...
This paper proposes a novel concept of antenna arrays operating in multiple-octave frequency range. The antenna arrays ensure steady half-power beamwidth (HPBW) in 2

A novel concept of four-beam antenna arrays operating in a one-octave frequency range that allows stable beam directions and beamwidths to be achieved is proposed. As shown, such radiation patterns can be obtained when radiating elements are appropriately spaced and fed by a broadband 4 × 4 Butler matrix with directional filters connected to its ou...
